In 1 Corinthians 7:10-16, Paul is addressing another issue in his church at Corinth: the issue of divorce. He makes clear that divorce is not an option for the Christian (v11 - "she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife"). The only exception Paul mentions to the command of not divorcing is if the other spouse is not a Christian and leaves the Christian spouse for good (v15).
For those of you who are married, since divorce is generally not an option, I would encourage you not to say "I want a divorce" or other like phrases with your spouse, even when you're fighting. The moment you speak it out, the more of a real possibility it becomes in the mind of both you and your spouse. So guard your words toward one another and always lean toward reconciliation whenever possible.
Let's pray that we would take marriage and divorce as seriously as God does, and that at Thrive Church single people would find excellent life partners who love Jesus, love His church and love them. And may we always take seriously the covenant we made before God with our spouse.
